One of the first things I noticed about Dahlia when I met her was her tongue. It's hard to miss the fact that her tongue is not solid pink. It is, in fact, speckled with large blue marks.
The spots on the tongue has led many who have met her or seen her pictures to say "She must be part Chow." So is she really?
The site Chow Chow Welfare says on their page "The Truth About Those Black Tongues":
We...know that blue-black spots on tongues are very common in dogs - more than 30 pure breeds are known to have members with spotted tongues.
Spots on tongues are simply deposits of extra pigment, like birthmarks and freckles on people. Dogs often have spots of dark pigment on their skin, too, hiding under their coats. These spots can be large or small, many or few.
So there's the truth. Is your dog part Chow because he/she has tongue spots? Not necessarily. Many purebred dogs have spots on their tongues, including various retrievers and shepherds. In fact, they're so common in dogs like Golden retrievers, that they are not considered a fault in conformation events.
So what is Dahlia, exactly? That's anyone's guess, though we've seen some pretty strong indicators that she has some sort of herding breed in her ancestry, likely Border Collie though she could have Australian Shepherd as well as or instead of collie. We've also guessed, from personality, coat, and looks, that she is part retriever, with Golden Retriever being our current #1 educated guess.
